Enum dbs_address_space::AddressSpaceRegionType

pub enum AddressSpaceRegionType {
    DefaultMemory,
    DeviceMemory,
    DAXMemory,
}

Type of address space regions.

On physical machines, physical memory may have different properties, such as volatile vs non-volatile, read-only vs read-write, non-executable vs executable etc. On virtual machines, the concept of memory property may be extended to support better cooperation between the hypervisor and the guest kernel. Here address space region type means what the region will be used for by the guest OS, and different permissions and policies may be applied to different address space regions.

Variants

DefaultMemory

Normal memory accessible by CPUs and IO devices.

DeviceMemory

MMIO address region for Devices.

DAXMemory

DAX address region for virtio-fs/virtio-pmem.

Trait Implementations

impl Clone for AddressSpaceRegionType

fn clone(&self) -> AddressSpaceRegionType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AddressSpaceRegionType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<AddressSpaceRegionType> for AddressSpaceRegionType

fn eq(&self, other: &AddressSpaceRegionType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
